1. A method of screening a tagged library of diverse compounds, wherein said library comprises a plurality of different members, each member comprising:
- a solid support;
multiple copies of a compound bound to each of said supports, wherein the compound bound to one of said supports is different from the compound bound to selected other solid supports, and wherein said compound comprises a peptide; and
one or more identifier tags bound to each of said solid supports, wherein said tag identifies the compound bound to said solid support or identifies a reaction said solid support has experienced, and wherein said tag is an oligonucleotide or a fluorescent tag, said method comprising the steps of;
a) cleaving at least a portion of said compounds from said solid supports to yield a collection of untagged soluble compounds wherein said tags remain bound to said solid supports;
b) incubating said collection of untagged soluble compound s with a receptor under conditions conducive to binding of a ligand to said receptor; and
c. c) determining whether any compounds of said collection have bound to the receptor.

- 12. In a method of synthesizing a synthetic peptide library comprising a plurality of different members, each member comprising a peptide composed of a sequence of amino acid monomers linked to a bead to which bead is also linked one or more oligonucleotide identifier tags identifying the sequence of monomers in said peptide, wherein said amino acid monomers are protected with Fmoc and piperidine is used to remove the Fmoc protecting group, the improvement comprising effecting Fmoc removal by treatment with 5 to 15% piperidine for 5 to 60 minutes or 15 to 30% piperidine for 1 to 30 minutes.
