20 feet of wall space = about 6.5 units of 3 feet long shelving = 19.5 shelves x 7 shelves per unit = 136.5 YARDS of shelving, or about 410 feet of shelves, or (using Ye Olde Librarian's Rulee Of Thumbe, room for about 9,000 volumes. In the NEW shelves. There's shelving for about another 1,000 volumes on the shelving already there in the Family Room in the basement, plus room for about another 500 volumes in the Dining Room, plus bookshelving we already have in storage for about 1,000 more volumes = shelving for about 12,000 books (more or less, depending on hardbacks/paperbacks, etc.).

Thats only for books. Doesn't count the shelving for for LPs, CDs, cassettes and other media.

Plus Internet drops for a cable modem in two rooms.

Anyone want to come help shelve books???
