Why can’t ChemExpo provide the original Data Documents?
Data documents can’t be directly provided by ChemExpo without copyright infringement. However, ChemExpo provides on the data document page a link to the original URL from which the document was obtained. PudMedIDs and DOIs are also provided where they are available.
Why can’t the data document be found at the link provided?
The location at which an organization or a manufacturer provides a document may change over time. ChemExpo also provides a link to a Google Search for the document title to aid users in locating the document if it is still available elsewhere.
How often is/will ChemExpo be updated?
The ChemExpo application will have updates as needed and as resources become available. The data in ChemExpo, however, is expected to be updated bi-annually.
What kind of updates can be expected in the future?
Updates to the underlying data in ChemExpo are planned as more information is collected and curated. Based on beta testing, some updates to the application itself may be planned based on available resources.
