Two more resources...
Yesterday in the shared DIY storefront thread below, Ivy Alvarez pointed to Chapbook Finder, another resource website for (not necessarily DIY) chapbook publishers & collectors. (Thanks, Ivy!) The site seems fairly new, but already contains a list of publishers, a links page (that points to Wild Honey Press's chapbook stitching demo), & a spot for individual chapbook descriptions that may evolve into something like a shared catalog or recommended titles feature. I've added them to the sidebar under "Stores, Distributors, Directories & Reviews."
The editors can be reached at chapbookfinder [at] aol [dot] com.
Poking around on the Poets House site yesterday, I noticed they use a service called Link Baton which directs readers toward a CHOICE of online retailers for each linked book, & can set cookies to remember preferred stores. I played around with it some. It's pretty cool. We might be able to incorporate Link Baton into a shared storefront too. (Unfortunately it will only work for books with ISBNs though.) It also seems like a handy feature for blog recommendation/reviews too, and it's designed to let you use it & still get credit for your affiliate referrals, if you're getting commissions from Amazon, Powell's, etc. (I've linked to the webmaster page pertaining to book-linking, but Link Baton also works for stocks & journal articles & publishers might want to read this page too.) Link Baton's been added to the "Other Resources" list in the sidebar.
