- View genotypes and descriptions of commonly used strains.
- American Type Culture Collection (ATCC) maintains yeast stocks and clones.
- EUROSCARF, the EUROpean Saccharomyces Cerevisiae ARchive for Functional analysis, maintains a collection of systematic deletion strains searchable by gene name.
- National Collection of Yeast Cultures (NCYC) maintains over 3,100 non-pathogenic yeasts, including type strains, strains of general interest for education and research, strains of industrial importance, and genetically marked strains.
- Common Access to Biological Resources and Information (CABRI) includes catalogs from European culture collections for yeast and other organisms.
- Addgene is a non-profit plasmid repository that distributes many plasmids for yeast research. In particular, Addgene is distributing a collection of Yeast Advanced Gateway Destination Vectors created by Dr. Susan Lindquist's laboratory.

- Yeast GST-fusion Collection developed in Eric Phizicky's laboratory. A total of 6080 individual yeast strains, each containing a plasmid expressing a different full-length yeast Open Reading Frame (ORF) fused to a glutathione S-transferase (GST). Hosted by ResGen Invitrogen.
- Yeast Knockout (YKO) Collection from the Saccharomyces Genome Deletion Consortium.
- Yeast-TAP Fusion Library from Dr. Erin O'Shea and Dr. Jonathan Weissman at UCSF, containing open reading frames (ORFs) tagged with a high-affinity epitope and expressed from their natural chromosomal locations. Hosted by Open Biosystems.
- Yeast Tet-promoters Hughes Collection containing 800 essential yeast genes for which expression is regulated by doxycycline. Hosted by Open Biosystems.
