Insider Named RootsTech 2011 Blogger

I’ve been named an Official RootsTech 2011 Blogger! This is quite an honor. RootsTech is shaping up to be an exciting event. The conference is scheduled for 10-12 February 2011 at the Salt Palace in Salt Lake City.

The two national conferences, NGS and FGS, have found West coast conference facilities so expensive that they rarely come out this way. Last year’s NGS conference demonstrated the unfilled demand.

The conference also fills the vacuum left by the demise of the GenTech Conferences of many years ago.

RootsTech replaces the trifecta of spring BYU conferences: the Conference on Computerized Family History, the Family History Technology Workshop, and the FamilySearch Developers Conference. Since the three conferences targeted different audiences, it will be interesting to see if conference organizers can effectively address each audience’s needs.

The BYU conferences failed to meet demand because of the limited size of the BYU facility. Attendance had to be capped. Classrooms were too small. Exhibitors were divvied up into small, far-flung rooms. General sessions were divided among multiple rooms. Moving into the Salt Palace Convention Center will make it possible for all who wish, to attend the conference.

Early bird registration is $99 through 7 January 2011. At that time the price goes up to $150. For more information and to register, visit http://www.rootstech.org .

Monday Mailbox: Printed Research Guides

Dear Ancestry Insider,

The state and country research guides have been moved to the FamilySearch wiki. That's a good way to keep them up to date. Unfortunately they've created no way to easily print them. That's a really ill-conceived development. A lot of people like to have printed guides that they can look at when their computers are turned off.

From Anonymous*

Dear Out of Print,

I thought a bit about your comment last night. For us who live all day in the computer, it is too easy to dismiss your concern. You know our type. If we don’t have at least two gadgets on our selves at all time, we start to fidget and wring our hands.

I remember experiencing your same feelings. I went to college between punch cards and personal computers. All we programmers printed our programs when we left the computer lab early each morning. We poured over those printouts for the hours we were out of the lab. We wrote new code in pencil in the margins and marked up the lines of arcane symbols, only to return to the lab that night, enter the changes and repeat the cycle.

Once I graduated to full-time employment my program printouts exploded in size from a dozen pages to hundreds of pages. I quickly found myself alone by the printer, watching the group’s entire paper budget emerge from the machine. It took quite some time to adjust to the small window my computer screen afforded into a document I previously viewed unfettered.

Unfortunately—well, actually fortunately, man’s accumulation of knowledge is like a gas, expanding to fill the space allotted it. The 40 page research guide of the 90s has now expanded, probably ten times or more. Guides previously restrained to country or state coverage now extend to counties, provinces, and municipalities. Printing out all the pages corresponding to an old paper guide is not only super inconvenient—as you may have found—it is completely impractical.

I have no easy answer for you. If a compelling number of people were willing to pay $20 or $30 bucks for a printed guide of hundreds of pages, a FamilySearch affiliate might try to fill the vacuum.

Short of that, I think you’re going to be stuck with printing your own. You will have to reset your expectations, settling for a much less desirable solution than afforded in the past. Don’t even think about printing all the pages replacing a hardcopy guide. Be choosy. Print only the articles that you need offline, short term.

That’s all I’ve got. Does anyone else have suggestions?

Signed,

The Ancestry Insider

We Want Tech: Automatic Citations

At the 2010 NGS Conference GenTech Luncheon David Rencher presented “The Top 10 Areas Where Technology Can Still Make a Real Difference in Genealogy : Could You Please Hurry?” In “We Want Tech and We Want It Now” I review technologies already available, at least in infant form. Today I look at:

#10 – Internet Citation Download

David complained that the download of a source document from the Internet should include citation information. I share David’s frustration here. But for some collections Ancestry.com and FamilySearch still don’t display complete citation information. Little wonder they haven’t worked on the exchange of citation information with tree management programs.

The good news is, automatic citation download is starting to happen outside the genealogy industry. The bad news is non-published sources are not well supported.

Zotero extends your Firefox browser, allowing you to automatically collect, manage, and cite Internet sources.

Perhaps the most important feature of Zotero is its ability to sense when you are looking at an item (or items) on a web page. For instance, if you are looking at the record for a book on an online library catalog, Zotero’s book icon will appear in Firefox’s location bar (at the top of the browser window, where the current web address, or URL, appears), like so:

Simply click on the book icon and Zotero will save all of the citation information about that book into your library. …

Zotero senses information through site translators. Zotero's translators should work with most library catalogs, some popular websites such as Amazon and the New York Times, and many gated databases. Just look for icons in the location bar. (For more information or for some sites to try out, see our Compatible Sites list.) The Zotero team will be adding support for additional sites over time.

If Ancestry.com and FamilySearch won’t support citation exchange, maybe we can talk Zotero into adding site translators for Ancestry.com and FamilySearch.org.

For more information about Zotero, check out http://www.zotero.org .

Citation Assistance

There are a number of websites that assist in generating citations, but they are pretty much limited to published materials:

• EasyBib is an Internet site that can assist in generating citations. For more information, visit www.easybib.com.
• BibMe is a free website with an automatic citation formatter that supports MLA, APA, Chicago, and Turabian formatting. BibMe leverages WorldCat external databases to auto-fill citation information. BibMe will format citations and compile a bibliography according to the style manual. For more information, visit www.bibme.org.
• Landmarks Son Of Citation Machine is a free website that formats citations. Select the source type, fill in the form, and the website automatically formats the citation. See http://citationmachine.net.
• OttoBib is a free website that creates book citations based on ISBN.
• NoodleBib is a research assistance tool that includes citation entry.

Beta.familysearch.org Replaces www.familysearch.org

The change is now official. The beta.familysearch.org website has “gone live,” replacing the old www.familysearch.org. For several days I have been reporting signs that the change was eminent.

The official announcement, “FamilySearch.org Website Changes,” came last night at 5:25pm.

If you haven’t yet, read my earlier article, “Comparing the Old and the New,” for a brief summary of what works and what doesn’t.

Initial feedback is somewhat polarized and can be grouped around these sentiments:

• What happened to (blank)? Fill in: IGI, PRF, Ancestral File, Historical Books,… (Aren’t you glad you read the Ancestry Insider? :-)
• It looks great, but…
• Don’t like changes. It is harder to use.
• Search used to be much better. (Do I hear Ancestry.com chuckling?)
• Wow! More records!

Some of the comments make you wonder. I thought this one was interesting:

“What happened to the ability to make changes to our own previous submissions?”

What do you think of the new site? Ready for prime-time? What needs to be fixed before FamilySearch shuts down the old site? Do you have favorite bookmarks that are now broken? What kudos can you give?

Comparing the Old and the New

Saturday morning another uncertain indication showed up that beta.familysearch.org will go live this month. This comment showed up temporarily on the FamilySearch Wiki early Saturday morning:

The FamilySearch Wiki Engineering Team modified a link on this page so it will not break when the Family History Library Catalog changes in late December.

The comment and the modification disappeared before the end of the day.

Documentation on beta.familysearch.org goes through the features of the old FamilySearch.org and gives a report card, of sorts, noting differences or deficiencies with the new FamilySearch.org website. I’ve added my own candid take, below.

To you, my friends outside FamilySearch, remember that these are my personal opinions and I do not speak for FamilySearch.

To you, my friends inside FamilySearch, I mean no offense. I know you care for quality, are aware of the issues, and are working to fix them. I have faith in you and ever growing respect. Although you may hear some things here first, I only repeat publicly available information.  My criticisms are offered as a service to our users.

Feature from old FamilySearch.org	Status of the feature on the new beta.FamilySearch.org
	The logo works as it did before, taking you back to the home page. The new website does not have a home button. I hear users saying they want it; I’m surprised FamilySearch hasn’t complied.
	Search Records, Advanced Search, and RecordSearch pilot have all been replaced with Historical Records search. Surprising, there are no links to this central feature of the new FamilySearch.org website. None in the header. None in the footer. Here’s an insider tip: Click the FamilySearch logo.
	I wrote about the FHLC after the November release (here and here). Product Manager, Robert Kehrer, responded with additional information you’ll want to read. (Thanks, Robert!)
	The new FamilySearch.org website provides no way to search Historical Books and no link to search them on the BYU website. There are links to individual titles in the Family History Library Catalog. The documentation states, “You cannot currently search the historical books directly.” I hope that means FamilySearch is planning on adding Historical Book search.
	Google and other search engines do a far better job of searching other websites. Further, it is beyond FamilySearch’s ability to maintain a categorized directory of genealogy websites. With the FamilySearch Wiki, FamilySearch has given users the ability to provide, categorize, and maintain links to other websites.
	The new website’s Ancestral File has Individual view only. Pedigree and family views are coming. Thankfully FamilySearch has concentrated on higher quality historical records and readying the new FamilySearch Tree for public use. Hopefully this meager effort to include Ancestral File is but a placeholder for the latter.
	The 1880 U.S. Census is present on the new website, along with additional years! Some minor losses of functionality have occurred, including links to subscription websites, where the images were free for some FamilySearch accounts. (BTW, the image links on the old website no longer work. But I digress…) The 1881 British Census is not available on the new website. Use the old one. The 1881 Canadian Census is present, along with additional years!
	As I’ve mentioned before, the good stuff—the extraction records—have been moved into FamilySearch Historical Records, available on the new website now. Patron submissions were moved to the new FamilySearch Tree. I’ll have a lot more to say about the IGI.
	Not added yet. Users are instructed to use the old website. Ditto here my comments about Ancestral File.
	The US Social Security Death Index was added to FamilySearch Historical Records last week!
	The Vital Records Index is present, but incomplete. I tried one record from each of the five countries. Twenty percent of my teeny, tiny unscientific sample were missing. Has FamilySearch compared batch counts to know how many records are missing? *  Mexico: Albino Perez *  Denmark: Lars Peter Johansen, 19 Oct. 1877; Sigersted, Sorø, D. -  Finland: Matt Johansson, 12 Sep 1867; Sippola, Viipuri, Finland *  Norway: Ellen Johannesdatter; Askim, Ostfold, Norway *  Sweden: Nils Johansson, 5 July 1801;Stånga, Gotland, Sweden
	I don’t get it. If Historical Records are the central feature of the new FamilySearch.org website, then FamilySearch Indexing is its lifeblood. The FamilySearch Indexing page is buried two links under the home page. The first link is secret. The second is hidden. Should you solve the mystery of the first, secret link, don’t bother clicking the big “FamilySearch Indexing” title or the large, beckoning image. The link is hidden after a couple of paragraphs into the page text. Insider tip: Click Give Back in the row of links near the top of any page. Then click Get Me Started. (On second thought, don’t get me started…)
	“Share My Genealogy” is not present on the new website. Ditto my comment on Ancestral File.
	Research Helps have been copied into the FamilySearch Wiki and in many cases improved. Click Learn, then search for the topic of interest.
	Research Guidance is a virtual reference consultant found on the old FamilySearch.org website. “Chatty Cathy” (as we sometimes call her) asks you a series of questions about an ancestor and then gives you an ordered list of records to consult, based on the locale, time frame, and the vital event of your ancestor. Because Research Guidance has long been the hidden gem, the Cinderella stepchild of the old FamilySearch.org website, I fear Cathy won’t find her way to the new website.
	The Wiki is not really a part of the old website. It is part of the new website.
	Ask a Question is a link to the Forums, also a new, not old, website.
	The online research classes have been copied to the new website. Click on Learn, then click on a link you can’t see until you scroll the page down. Don’t scroll too far or the link will disappear off the top of the page. Don’t scroll too little or the link will not appear. Do a Goldilocks scroll. Don’t click “Research Courses.” The color looks like a link to me, but it is not. Keep reading, scrolling if necessary. Insider hint: Click on View the Courses.
	Find information about the Salt Lake Family History Library by clicking on FamilySearch Centers, scrolling to the bottom of the page, and clicking the hidden link. Insider Hint: To find hidden links, move your mouse around over possible spots. When the cursor changes (a pointing finger on most browsers), it is pointing to a link.
	To find a nearby family history center, click on FamilySearch Centers, enter the location, and click Search. Notice the snazzy new map.
	“The site currently does not provide information about genealogical institutes, university and home study courses on family history, online genealogical presentations, and upcoming genealogical conferences. Much of this information will be available in future updates of the site.”
	This is redundant. I covered it in the Search Records menu.
	It looks like the same Help Center software added a few years ago to the old website, and used on the new FamilySearch Tree website, is being used on the new site.

To learn more about the differences between the soon-to-be new www.FamilySearch.org and classic FamilySearch.org, start at beta.familysearch.org, click on Help, then “What are the Differences between Classic FamilySearch and Beta FamilySearch?” Use the interactive guide. And click “View or Print Handout” to access “Adjusting to the New Version of www.familysearch.org (8 December 2010).”

FamilySearch Poised to Replace www.familysearch.org

Indications are surfacing publicly that FamilySearch is readying to replace www.familysearch.org with beta.familysearch.org possibly before the end of the year.

“[The] FamilySearch website will change to a new version by [the] end of 2010,” says a December newsletter sent to Salt Lake area family history consultants of the Church of Jesus Christ of Latter-day Saints. The newsletter excerpts a document made public by FamilySearch titled Adjusting to the New Version of www.familysearch.org (8 December 2010).

The document outlines the differences between the previous site and the new site and explains how to perform tasks commonly done on the old site.

“The updated version of the FamilySearch website gives you a richer family history experience by putting all FamilySearch content, services, and products on the same site,” according to the document.

Not everything has been moved to the new site yet, such as the Pedigree Resource File. “Until it is available, scroll to the bottom of [the] screen, and click Use the previous version of FamilySearch.org.”

“The Social Security Death Index will be added to the website on or shortly after 10 December 2010.”

I’ll report more as I have time. Stay tuned…

Mailbox Monday: Stitching

Comments about last Wednesday's article, "We Want Tech: When You Can't Stitch":

---

Dear Insider,

Maybe I am misunderstanding what you see as a problem here, but ...

Both versions of your stitched map have an inverted keystone shape, suggesting that the lower part of the map was photographed at camera level and you tilted the camera up to get the upper part. Tilting or panning works if you are stitching a landscape, but to get a square document to come out square in the stitching you have to move the camera to keep it pointing directly at the center of the part of the document you are currently photographing.

Dear Anonymous and Misunderstood,

You are correct that the bottom half of the Halifax map was shot straight on and then the camera, mounted on a tripod, was tilted upward for the upper part.

But you are only partially correct assuming that the stitched result won't be square if the individual photographs are not square. Look back at “We Want Tech: Stitching Folio Size Documents.” The photographs of the FHL wall mural were all shot from a tripod at a fixed point. Here is one:

One of the photographs

I used three levels of tilting and five positions of panning. The stitching program corrected the distortion and created a square result:

Distortion is corrected in the stitched image

Isn’t that amazing?!

Dear Insider,

Hello,

Stitching photos has been around for a long time and is hugely represented by many sophisticated software programs and even camera manufacturer's programs like Canon's software. There are some extensive sites online discussing the panoramic photo process. It looks like I will have to write something about this.

James Tanner*

Dear James,

I am so glad you’ve taken notice. Thank you for your article, “A Stitch in Time, in Genealogy, Saves Nine (Photographs).” David Rencher, myself, and everyone else looking for a solution are grateful. If you or anyone else want to take a stab at stitching David’s map example, I’ve posted the nine photographs on Flickr at

They are named “Drogheda Map Photo#”.

Tips for Using Image Composition Editor

The past two Wednesday’s I’ve talked about using Microsoft Image Composite Editor to stitch together photographs of a map or large document that was too large to capture legibly in a single photograph.

Image Composite Editor is not officially supported nor does it include a manual or a Help File. But it’s free! And if you are moderately technical, you can spelunk your way through it. Sorry; I’m too busy (or lazy) to field any questions you might have. Go ahead and post questions here and if another reader can answer, I invite them to chime in.

One thing that I wasn’t able to intuit was the editor’s four stitching modes. The editor calls them Camera Motions because each is optimized for a different camera scenario. The editor will automatically choose one for you, but you should try all four to see which gives the best results.

• Rotating Motion – Designed for pictures taken from a single spot.
• Planar Motion 1 – Designed for scans from a flat-bed scanner.
• Planar Motion 3 – Designed for level photographs taken from various positions.
• Planar Motion 2 – Designed for non-documents and skewed photographs.

Use a Tripod

If you can’t use a scanner, use a tripod.

The first Camera Motion is Rotating Motion and is optimized for a tripod. This is the Camera Motion that I used for the FHL wall mural.

Position the camera so when pointed at the center of the document the camera is square with the document and the lens is parallel to it. Said another way, there should be no tilt, pan, or rotation when the camera is pointed at the center of the document.

Images taken from a fixed point suffer from perspective distortion. Use the composition editor’s perspective controls to correct the distortion. Use the four steps in the illustration to the right.

 

 

That’s all I’ve got for you. Give it a whirl and see how you do. In Monday’s mailbox I’ll respond to feedback from this week’s articles.

We Want Tech: When You Can’t Stitch

How can Microsoft Research’s Image Composite Editor successfully stitch together 15 photographs of a large wall mural but fail on a 9 photograph map? (See last week's article, "We Want Tech: Stitching Folio Size Documents.")

I decided to try a map of my own.

To make the test as realistic as possible, I flew to the opposite side of the country, drove several hours to a small town in New England and took pictures of a wall-mounted map tucked away behind the coffee machine in the town hall (several rooms attached to the school house). I took three overlapping photographs of the map, drove back to the airport, flew home, and fed the photographs into Image Composite Editor.

It successfully stitched them, but distorted the map something fierce. (See the image to the right.) While passable for general purposes, it might be difficult to use for plotting metes and bounds. Click on the image to magnify it a bit. The full size image is 29 megapixels (4950 x 5879).

The Family History Library wall mural may have been much bigger, but it may have been easier to stitch because it is all orthogonal lines and boxes.

Back to Rencher’s Map

If you can’t stitch your map photographs, are there alternatives? You bet. Microsoft Photosynth is a photograph viewer that makes it easy to move from photograph to photograph based on their overlap. It’s a nice alternative to stitching. You zoom into any image as close as you need. You pan around the image. When you reach an edge, a ghost of the next image appears. Click on the ghost to view it—without distortion.

Below is an example Photosynth of Rencher’s map. I zoomed out far enough to see the ghosts surrounding the central photograph. This view reveals a problem that may have caused the failure in Image Composite Editor.

Notice the photograph that I colored yellow. It was shot closer to the map (or with greater zoom). It doesn’t overlap any other photo besides the one below it. It leaves a hole in the map. Further complicating things, I was working with low resolution copies of Rencher’s photographs. But even with these problems, Photosynth successfully positioned all nine images. Click the above image to see Rencher’s map of Drogheda, Ireland.

I redid my test map in Photosynth. Click on the image to the right to see the result. Compare it with the stitched result from Image Composite Editor at the top of this article. Do you prefer working with a deformed stitched image? Or with a non-stitched, non-deformed Photosynth?

Photography Tips

As we’ve seen, success depends in part on how carefully you take the photographs. Computers are stupid and easily confused. Try to keep things simple:

• Don’t change camera zoom between images.
• Keep the camera level.
• Light the document well and uniformly.
• Overlap adjacent images by an ample amount, perhaps as much as 25%.
• Use a tripod.
