New Dataset: Infogroup’s Historical Business File

Columbia University has access to the Infogroup’s Historical Business File via WRDS.

Infogroup gathers geographic location-related business and residential data from various public data sources, such as local yellow pages, credit card billing data, etc. The Infogroup database at WRDS contains two packages: Historical Business and Historical Residential, both of which largely focus on US sectors.

The Historical Business data starts in 1997, while Historical Residential dates back to 2006. The Historical Business data is a calendar year-end snapshot of local business data. It contains business identification, location, industry, corporation hierarchy, employment, sales, and other fields.

For more information about this dataset, please visit this page

Using Python, R, MATLAB APIs for Datastream!

Do you know that in addition to Excel API, now you can also extract data easily from Datastream by using Python, R, or MATLAB?

For Python:

PyDatastream is a Python interface to the Thomson Dataworks Enterprise (DWE) SOAP API (non free), with some convenience functions for retrieving Datastream data specifically. This package requires valid credentials for this API.

It is a Python API for time-series data which abstracts the database which is used to store the data, providing a powerful and unified API. It provides an easy way to insert time-series datapoints and automatically downsample them into multiple levels of granularity for efficient querying time-series data at various time scales.



Alternatives for other scientific computing languages:

Please note that only PhD students and faculty can request credentials. Please email if you had any questions.

[Metro SIG Meeting] Historical Corporate Annual Reports Digitization Project


This Wednesday, June 8 2016, Watson Library’s Interim Head Jeremiah Trinidad-Christensen was invited to make a presentation at the Metro’s Economics and Business Librarians SIG meeting about the Historical Corporate Annual Reports Digitization Project in Watson Library.

Jeremiah provided an excellent summary of this widely-used digitization project, which was conducted by a group of Watson Library staff, led by our Collection Development Librarian Yasmin Saira from 2007 to 2009. The audiences were hugely intrigued by the fascinating stories Jeremiah extracted from these reports; everyone was also amazed at the visualization he created in the end, using one of the historical NYC maps:

Thomson One: Workaround for using Chrome and Firefox

Thomson One is a useful database for financial data on public companies, as well as merger and acquisition information and market data. Users can search and screen across databases to identify companies that meet your specific investment criteria as well as conduct peer analysis.  Includes Investext, Private Equity database (Venturexpert) and Thomson Deals (SDC Platinum).

However it proves to be difficult because of its compatibility with only Internet Explorer (IE) pre-version 10.  However this is a workaround with an extension/Addins for Chrome/Firefox.

Please note that not all functions are supported with this solution (i.e. downloading analyst reports).

Please note, this information was gathered from a various business libraries.
