Well there may be more which I may not have explored. Prices of plans are almost similar. But I think the biggest concerns I had with depth of the books. I prefer reading non-fictions and at some point I realise they really do not have that great a catalog. Even if they have you may get them late. But in any case I will still prefer this option over buying books. Actually, typical books one never buys for long term reference. You only read the book once and then it sits in your book rack for display till the content validity expired. This is particularly true with many management books. You realise some real praises on ability for financial sector to securitise the mortgage assets and one bubble burst you realise those theories may not be all relevant in the world of subprime lending. I kind of feel these libraries do a fair share of service there. They reduce the clutter and they create a critical mass of readership for you to know which books to pick up and which are not. However, sometimes when you get the book you realise a lot of water has flown below the bridge. I think that gives me time to identify a book of depth vs. a temporary fad though.
Now that MyLib and my association for past 4 years is no longer an option which one should I choose. I guess I will wait for sometime. Have got a whole series of John Grisham to finish before I look upto some new texts. It may be worthwhile to give me a library vacation for sometime before I decide on one.
