General introduction to APIs and how they might be used in a library. Characteristics of APIs. Examples

1. API opportunities
A general introduction to APIs
and how they might be used
at the Watson Library

2. API opportunities API e.g.
Application:
Open Library Data
Program:
“FindIt Catalog”
Interaction:
Application hosts
images. It accepts
requests for an image
with ISBN match.
Program can display
the book cover image
if the application
provided one.

3. API opportunities
Application:
Google Books
Program:
“FindIt Catalog”
Interaction:
Application hosts
book descriptions. It
accepts requests for
information from
programs.
Program can display
the book information.
API e.g.

4. API opportunities
Application:
Internet Archive
digital collection
Program:
“FindIt Catalog”
Interaction:
Application hosts
digitized books. It
accepts requests
from programs.
Program can display a
link to the digitized
book.

An “API” is a defined interaction between that part of a
computer application which accepts requests from
other programs and responds by providing some data.

to know about
Application Program Interactions

7. API opportunities
In order for a program to interact with an API, it must follow well
defined, well documented syntax for making requests.
We saw the book cover in the library catalog. That API request
looks like this …

Secondly, note that the response from the application is data…
<breakfast_menu>
<food>
<name>Belgian Waffles</name>
<price>$5.95</price>
<description>Two of our famous Belgian Waffles with real maple syrup</description>
<calories>650</calories>
</food>
</breakfast_menu>

9. API opportunities
FoLok
or as JSON data …
{"request_date":"2017-11-14 15:26:52.195","search_value":[
{"operator":"contains","field":"Index","value":"c"}], "search_type":"search","results":

• Some APIs only accept requests from authorized programs.
• In that case you have to register for an “API Key” first.
• The “key” is sent as part of the request.

API Key

11. API opportunities
Lastly, your program will need to have coding that tells it how to
parse the data and do something useful with it …
def make_openlib_holding(book):
holding = {
'LIBRARY_NAME': 'IA', 'LOCATION_NAME': 'OL’,
'LOCATION_DISPLAY_NAME': 'OL: Open Library’ }
if book.keys():
holding['ITEMS'][0]['DISPLAY_CALL_NO'] =
book.get('identifiers', {}).get('openlibrary', [])[0]
holding[‘DATA = book.get('url', '')
return holding

12. API opportunities @ Watson
Benefits of using APIs @ the Watson Library
• Help the library / museum staff do their work
• Improve usability of our services for library patrons
• APIs might be used advocate the value of the library to the
museum and the community by providing informative
‘dashboards’

13. API opportunities
Types of info we can get or update from Sierra
RETRIEVE ADD or DELETE
UPDATE
• Bibliographic data
• Item data
• Order data
• Patron data
• Checkouts
• Fines
• Holds
@ Watson
• Hold data
• Patron names
• Addresses
• Phone numbers
• Emails.

18. API opportunities
What’s next?
• Let’s learn what APIs are offered.
• We can network with the Sierra and TMS community of API
developers from other libraries
• We’ll form a group of library staff to brainstorm ideas –
and set priorities for which ones we might try first.
• APIs are powerful, and free, let’s use them!
