I use the following libraries:
- Filing - Miscellaneous news articles and reference information that I want to save. It’s mostly Web archives with some PDFs.
- Financial - Receipts, rebates, order confirmations, credit card and bank statements, invoices, tax forms (blank and completed), research for major purchases.
- Lists - Archives for the tons of mailing lists that I subscribe to. Searching technical mailing list archives is often a better way to answer questions than asking Google. Some lists I read completely. Others I archive if I think they might be useful someday, e.g. a technology that I think I’m going to want to learn.
- Mentions - Web pages, articles, podcasts, etc. that discuss my software products.
- Personal - Archive of non-list e-mails, including both sent and received messages.
- Publications - Electronic publications, mostly PDFs.
- Spam - All the spam messages I’ve received since early 2002.
- SpamSieve - Articles and academic papers pertaining to spam filtering and text classification, as well as a collection of interesting spam messages that I’ve annotated.
Note that the libraries are mostly separated this way because this is how I had organized my files in the Finder before EagleFiler existed. At some point, I may combine a few of them, e.g. so that mail, Web archives, and PDFs pertaining to the same topic are grouped together.
