Display in OPAC of Different datatypes

⚠️

Diagnosis: Your Koha is defaulting to "text" because the Item Type Codes in your MARC (952$y) do not match the codes in your Koha Administration.

Solution 1: Define Item Types in Koha Admin

Go to Koha Administration → Item types and create these entries exactly as they appear in your MARC data:

Code (Must match 952$y)	Description	Suggested Icon
BK	Book	bridge/book.gif
ARTICLE	Journal Article	bridge/periodical.gif
THESIS	Research Thesis	bridge/thesis.gif
BIBLIO	Bibliographic Entry	bridge/reference.gif

Solution 2: Adjust MARC Leader (LDR) for Theses

If an item is missing, Koha looks at Position 06 of the Leader. To differentiate theses from standard books:

• Books/Articles: Set Position 06 to a (Language material).
• Theses/Manuscripts: Change Position 06 to t (Manuscript language material).

MarcEdit Fix: Click the LDR field → Type of Record → Select "t-Manuscript language material".

Solution 3: Enable XSLT System Preferences

Ensure your system is configured to show icons in the OPAC:

1. Search for DisplayOPACiconsXSLT → Set to Show.
2. Search for OPACNoItemTypeImages → Set to Show (this enables images).

Solution 4: Collection Codes (CCODE)

To see "Sirah Hub" or "SNK Bibliography" clearly next to the item type, add Collection Codes:

1. Go to Admin → Authorized values → CCODE.
2. Add values: SIRAH (Sirah Research Hub) and SNK (Sher Nowrooz Khan).
3. Add the tag to your MARC: =952 \\$8SNK

Standardizing these administrative settings ensures your scholarly Hub is visually organized and professional for researchers.
