I have recently been building a birding and natural history library from books available on the internet. Many of the old books about Texas are available as are journal articles from recently and long ago. Several relatively new sites offer large number of bird and other nature and science related books and journals. It is surprising how much about early texas is available in the British ornithological journals. Two major sites are used by libraries and universities that scan old books and make them available online. Texas universities are starting to take part with a current emphasis on non-bird material such as the complete set of the Texas Conchologist but Strecker's original texas checklist is there and journals of the early explorers with notes on natural history. Biodiversity Heritage Library with 2,820 bird related books. It has more journals than the other site. http://www.biodiversitylibrary.org/Default.aspx All of the books on this site can be downloaded. For hummingbird fans, Gould's monograph on the family complete with all pictures is there as is Audubon's Texas journal and his birds of america is being added. Many year of reading on rainy or really hot days. Or you can revert to your childhood and go out in the field with Reed's little green bird guide or Forbush's New England Guide. Many other pre-peterson "id" are here. Try identifying birds with the books that Peterson replaced and the limits that any bird-watcher had back in the old days. Hathi Trust is more difficult to use as non-members can only look at books by page (5,181 bird books) or search books (another 9,761 bird books). Apparently you have to have access through an organization such as a university to download entire books. http://catalog.hathitrust.org/ Google has a project to scan and make available all old books but many of its scans are not as good or you have to pay to read them. The google books are available through many sites, some paid and some free. The old standard book site is Project Guttenberg which has a goal of providing 1,000,000 books for unlimited free use in all standard formats. They are starting to add the Bent Life Histories with the warbler volumes just added http://www.gutenberg.org/wiki/Main_Page Many of the journals and exploration books about the west and texas are there too but the site has specialized in fiction and history etc. more than scientific type books but is adding more in books like Bent. And finally the Open Library project has been updated to make bird books easier to find. It also identifies which are available as ebooks. The site is a library search site so that the normal use is to find out which library will lend the book or make it available in the stacks. Many of the books cannot be used online but more and more of the ebooks can be downloaded. The site only has 2,573 bird books but includes Aristophanes. http://openlibrary.org/search?subject_facet=Birds&subject_facet=Accessible+book Some newer books are out there too. Paul Johnsgard has made his books including Birds of the Great Plains which covers the panhandle, and his duck and crane books free online at http://digitalcommons.unl.edu/johnsgard/ It is important to remember that while many of these books can be used freely, they cannot be distributed freely. So you can download and read or add them to a library but they cannot be distributed to others etc. For many there is a long chain of copyright and other limits of use such as when Harvard lets Google copy books, a google user edits the raw google copy and adds it to an online library which is then referenced from another site. There are 2 basic books types available. Ebooks are the new book format that can be used on all computers, pads, phones etc. Depending on the source, the books may be available in proprietary format such as those purchased from Amazon or Barnes and Noble. The epub format is the general free use format that can be used on all computers, phones etc except where the hardware maker bans them. The other book format is adobe files which can include material typed like an online help file and would appear very much like an ebook. Or, and this is the source of most of the old books, each page of a book is scanned and the scanned pages are compiled into a pdf file which can be used on almost all devices. Books like Gould's Hummingbirds are done this way. The best way to build a library is on a computer as it has room for many books and many of those are large. I use Calibre which is a free open source program that lets you index and sort and do whatever you want with all of your books. Even better it lets you readily convert books from one format to another. It is upgraded and improved almost weekly. http://calibre-ebook.com/ You can download the free epub Bent Warbler book from Guttenberg and convert it for your kindle, iphone or whatever you have. Likewise you can take a kindle book and read it on your computer or another device. Again be sure to read and follow the copyright rules on your books. All of the books can then be exported to your phone or pad. Even better you can download any web pages out there and import them into Calibre where you convert them into a short book. For example there are a couple of web sites that provide guides to birding in the Rio Grande Valley. They are not very helpful way upriver where there is no reception but the converted guide to say Falcon State Park can be used offline. Again it saves data charges if that is important. Again, even more important, the web sites belong to the owner of the site as does all the information so make sure that your use complies with what is legal. As an example, I can go to my website and select the 2012 hawk watch page, save it to my computer as an html web page to my computer, drop the downloaded file onto calibre, convert it to an epub, export it to my iphone and I have a book to show visitors to the hawk watch tower what I have seen and photographed this year. I can send the same page to any kindle, android phone or other device too. Great for the times the cell service is less that useful. Or you can do a little cutting and pasting from sites like texbirds, ebird etc and have maps, detailed instructions of where to go, pictures and the latest news about a rare bird out in big bend where you really do not get phone service. But again, be sure to know what the use rules are for the sites. Most allow personal use but not any form of shared use without permission. Lots of good reading out there. -- Joseph C.
