How to use Summon

The Summon™ discovery system can be accessed from any PC that is connected to the Internet, using the following address:
For more information on contents, see the About page or write to:

Selecting a language

Summon™ is available in Italian and English; to switch from one language to another, just click on the drop-down menu in the top right corner on any page:

1 - Summon selecting a language

Choosing a language is linked to the search engine interface, not to bibliographic content, which is identical for both versions.

Simple search

The first type of search is a simple search:

2 - Summon simple search

Enter the keywords (always leaving out articles and prepositions) to be searched in all fields. Simple searches insert boolean operators by default AND among the different words. You can search specific fields using the syntax: field:(keyword). For example, the search ISSN:(1234-5678), will identify records containing the value specified in the ISSN field.

Some of the search fields that can be used are:

  • Title
  • Author
  • ISBN
  • ISSN

Advanced search

Another type of search is an advanced search, which allows you to enter additional terms in specific fields and use other filters:

3 - Summon advanced search

  • enter the term or multiple terms to search in the desired fields
  • choose the appropriate filters below (optional)

Jolly characters

If you do not know the exact term or you want to extend the search to include variations of a specific word, you can enter the term shortened by a few characters, adding an asterisk as a jolly character: for example, entering econom*, will retrieve results for economyeconomieseconomics, etc.

To research a specific phrase, enter words in quotation marks: for example, if you enter "Camp David 1978", the only records that will come up will be those where that term appears exactly in that form and that order.

Use of boolean operators

By default, all search terms are combined with the operator AND, but other operators can be used to make the query more specific:

  • AND (presence of both terms: A and B)
  • OR (presence of both terms or at least one of the two: A and B, A, B)
  • NOT (presence of the term A or B, but not of A and B together)
  • + (immediately before a term to indicate that it must always be included: A+OR C, B will always be in the results)
  • (like OR: presence of both terms or at least one of the two: A and B, A, B)

Search results and how to save them

Ten to fifty results can be selected, and can be ordered by year or relevance.

Results are presented in brief, showing only the essential data:

4 - Summon search results

  • for more details and to see a preview, click on the magnifying glass
  • to save the citation, click on the yellow folder
  • to view the entire text, where available, click on the title or on the complete text online

Saved citations are collected in a personal folder and can then be sent by e-mail or saved by clicking on saved items in the bottom right:

5 - Summon saved searches

Use of filters and facets

To further refine your search you can select one or more facets, located to the left of the results:

6 - Summon refine search

Use the filters to limit results to the documents available in full text or to articles in peer-reviewed academic journals, or to exclude articles published in newspapers.

7 - Summon content type

8 - Summon subject terms

Use facets to include or exclude specific bibliographic types or subject terms

9 - Summon publication date

10 - Summon language

or to specify language or year of publication.

The number of records relevant to that specific selection is reported in parentheses.

Results can be refined by applying multiple filters at the same time (additional subject terms as well as publication type and date), to allow you to see only the most relevant search results.

Types of documents

Summon™ contains different types of bibliographic records:

  • Articles from academic journals
  • Articles from magazines and newspapers
  • Conference records and reports
  • Books and chapters
  • Reviews
  • Theses and dissertations
  • Working papers

The full text is not available for all records; sometimes only the bibliographic citation is provided:

11 - Summon citation

Clicking on the title, another screen will open with bibliographic details and the possibility of doing another search:

12 - Summon citation 2

Clicking on search for document will bring up other searchable catalogs and the option of directly accessing online services for documents provided by the Library, such as document delivery (for periodical articles) or interlibrary loans (for monographs):

Other resources

Since not all resources can be searched using Summon™especially resourses in Italian, you should always consult the page dedicated to the Library’s databases (in Italian).
