Welcome to all of the newly NSF-funded Advancing Digitization of Biodiversity Collections (ADBC) projects. This year we have three new Thematic Collections Networks (TCNs) and six Partners to Existing Networks (PENs) joining the community.

2019 TCNs:

• Digitizing collections to trace parasite-host associations and predict the spread of vector-borne disease [1](TPT),
• American Crossroads: Digitizing the Vascular Flora of the South-Central United States [2] (TORCH), and
•  Enhancing Access to Taxonomic and Biogeographical Data to Stem the Tide of Extinction of the Highly Imperiled Pacific Island Land Snails [3] (PILSBRY).

and the 2019 PENS:

• Enhancing the SoRo TCN with collections of taxonomic, geographic, and historic significance from the Rancho Santa Ana Botanic Garden Herbarium [4] joining the SoRo TCN,
•  Functional Quantitative Characters for Ecology and Evolution (FuncQEE) [5] and The oUTCT PEN: Outwardly Mobilizing the UTCT Vertebrate Archive for Research and Training [6] joining the oVert TCN,
•  The Cretaceous World: Connecting the Cretaceous Seas of North America [7] joining the Cretaceous World TCN,
• Critical Central and South American additions to the EPICC TCN from the oldest Invertebrate Paleontology collection [8] in the United States joining the EPICC TCN, and
•  Integration of data from the San Diego Natural History Museum with the Lepidoptera of North America Network [9] joining the LepNet TCN.  

Welcome to the ADBC community, and we are looking forward to working with you!
