My wife has tried for years to get me to catalogue my library. She actually got me to agree at one point a few years ago to do it. She found some sort of software, which required me to enter all the pertinent data for each book. Over time I had succeeded in getting much of the library catalogued. That, however, was before the fire, which both destroyed the catalogue, and radically altered the size of the library. I still have a long way to go toward rebuilding certain aspects of my collection, but at least it has once again become delightfully sizable enough to really require organization. Nevertheless, I put it off.
Until recently. Ruth talked me into using an online cataloguing service, called Library Thing. I highly recommend this to anyone who would like an easy to use, reasonably priced system, which brings with it all sorts of literary networking possibilities. What do I mean by easy to use? If you simply enter the International Standard Book Number (ISBN), or the title, or the author, or the Library of Congress Number, the full record for your book will usually pop right up. You just click the right book, and it gets placed in your library. You can then add certain elements to your record, like tags, and reviews, etc., which I have only partially got into so far. Over all, it's the best, and easiest system I have even seen. There is a $25 one time fee for lifetime membership.
Library Thing would be an excellent way to go for individuals, or parish libraries, or schools, or whatever. If you look in the search feature, you can find libraries of all sorts and sizes. I found the library for Zion Lutheran Academy of Zion, Fort Wayne. (You can even find my library now.)
I am very pleased with this cataloguing system, and, again, I recommend anyone check it out, which you can do here.
